Measured Value Description Primary Secondary % Referenced to
V target
Calculated target voltage with
consideration of Z compensa-
tion
kV V Target voltage of the winding
referenced to the rated voltage
of the winding
The functional measured values V max and V min can be reset with the input indication
>Reset min./max.
.
For the two-winding transformer, you can find the measured values under the following menu items of the
device:
•
Main menu → Measurements → Voltage control 2w → 90V V.contr.2w
•
Main menu → Measurements → Voltage control 2w → Statistics → 90V V.contr.2w
